SIPHON QIRCULATING SYSTEM FUR AUTOMOBILES Filed April 15; 1927 sAMUEL KAYE, or COLUMBUS, Mrssssrrrr; B.' G. .HAZARD AND 4Roisin WEAVER nxEcUToRs or SAMUEL KAYE, sa.; DECEASED SIPHON CIRGULATING SYSTEM FOR AUTOMBILES l Application led April 15,

VThis invention relates to an improvement in1 siphon circulating systems for automobi es. i

. The object of the invention is to provide a greater ,circulating capacity through the radiator` and the water jacket of the engine than is ordinarily obtained. This is accomplished by providing a separating chamber, a mixing tube, vand a condensing chamber in the top of aradiator, an overflow pipe7V and a bottom hose connection between the radiator and the engine waterjacket of a capacity greater than that of all the radiator tubes combined, so as to keep a continuous circulation of water through all the radiator tubes. This causes the water to flow more freely and quickly into the engine water jacket and a continuous circulation therethrough. j

The invention further providesa mixing tube to thoroughly mix thev steam and water which passes'from the uppermost part of the engine water jacket. The mixed water and steaniforms a lighter mixture thanthe solid body oflwaterv in the radiator whereas the weight ofthe water causes this light mixture to rise above the level of the water in Athe radiator and flow,A over the 'top endwof. `themix'ing tube into the separating chamber, which is made a part of the radiator or else' connected thereto, and through one or two passages into the vcondensing chamber fof theradiator; where two pipesare used, one is for the passage of water and the other for the passage of steam, the steam passing F through the Vuppermost pipe into the con- 'densing chamber7 and out through'the overow pipe, the open end of which is arranged fat a point below'the upper or discharge endl 'of the mixing tube which extends into the lseparating chamber. u i j Thisv arrangement also preventsy any -water from Aflowing' back from Vthe radiator down through the rmixing tube into the top of the engine water jacket and insuresof a con- 'tinuous circulation through the radiator and .the natural system intended ior cooling the engine. v j v- 'n the accompanying drawings p Eig. l is a vertical sectional view-of 'aradiM 1927.

ator and aportion of an engine with the inp vention as applied thereto;

F ig. 2 is a top plan view of the same;

Fig. 3 is a detail .transverse sectional View; The numeral 1l designates the engine generally, 4which may be of any suitable form,

normally used to drive an automobile This l engine is provided with the usual formr of water jacket 2 shownesp'ecially in Fig. 1.

The' usual form-'of radiator is `designated bythe numeral 3 for cooling the' water- 'pass inginto the engine water jacket 2, and for this' purpose the radiator' isprovided -with an upper steamcondensingchamber il: and a lower radiator chamber ,"connected .etogether-by a series of small tubes 6, as shown in Figs. 1 and 2. The upper radiator chamber is provided with`a plurality of horizontal tubes 7 which pass through said chamber. When the car is moving, airpass'es through the said horizontal tubes 7, causing the steam in chamber `4 to partly or wholly,condense.

VThe lower chamber 5 is connectedv to the water .jacket 2 by means ofan 'enlarged bottom hose connection 8. The capacity of the connection Slisgreater than that of thecombined capacities of all of the vertical radiator tubes V6,*soV as to insurea more perfect circulation through the said tubes 2. .j

A separating chamber 9 may be formed intergral with, or separate from, the upper radiator chamber 4,*but is connected therewith by one or two ypipes or passages 10l and 11 for water and steam respectively.

A mixing tube 12 is connected with the en,

Vgine ywater jacket 2, and extends upwardly from the water jacket into the separating chamber9 to a point slightlyrbelow the-top ofsaid chamber.` l j The `lower end of the mixing4 tube-12 ex# tends into the water jacket 2, and is perforated as at 13 to allow ,the steam to enter the mixing` tube around its entire circumference and to thoroughly mix with the water which Aenters atnthe end. 'An overflow opening or vpipe 14 extends downwardlyl from the upper radiator chamber llaas-shown inF ig. 1,' and the upper end of this overflow pi eis 4arranged at a pint below the top or' `c scharge `end if :the raming tube 12, morder te pre bubbles created in the1engine water jacket rise to the uppermostp art thereof from where lthey pass into the mixing tube 12, where the steamand water are so thoroughly mixed `as to form a lighter-mixture than the solid body of water inthe radiator, thereby causing this light mixture to rise above the level of the water in the radiator and flow over the top end of the mixing tube into the separating chamber where the water and steam are separated by the water flowingbelow the top end of the' mixing tube, the water level=being maintainedat that point by the relative position vof-the inlet end ofthe overflow' pipe. `The most of the steamis condensed'in the condensing chamber 4, and the vremaining steam if any passes out through the overflow pipe 14.

The increase rin the size or capacity of the bottom hose connectionf? to a size greater than the Vcombined capacities of the radiator tubes'tends to cause the water to iiow more freely and quickly into the engine water jacket when the water in contact with the hot engine wallsbecomes so hot as to produce steam, thereby reducing the resistance of the water flowing out of the radiator and tend'- ing to cause the waterl to flow through more of the radiator tubes `thanwould be the case if; the latter had a greater capacity than the bottom hose connection, which tends to increase the cooling capacity ofthe radiator.
